Summary: Radeon driver reports EDID errors every 10 seconds Product: DRI Version: unspecified Platform: x86-64 (AMD64) OS/Version: Linux (All) Status: NEW Severity: major Priority: medium Component: DRM/Radeon AssignedTo: dri-devel@lists.freedesktop.org ReportedBy: teufel@cs.uni-frankfurt.de
Created an attachment (id=46512) --> (https://bugs.freedesktop.org/attachment.cgi?id=46512) an excerpt of /var/log/messages with some comments and an example of the output to tty1
Radeon driver reports EDID errors every 10 seconds, which causes related log files increased over 100M in size every day and makes the system hardly usable because of the output every 10 seconds to tty1 (and ttyS0 in my case).
See also my related LKML message: https://lkml.org/lkml/2011/4/14/661
I get every 10 seconds: radeon 0000:01:05.0: HDMI-A-1: EDID block 0 invalid. together with a block of zeroes (only on tty1, see attachment).
